120mm Knauf FactoryClad Roll 40 (Uncut) 9.4m x 1.2m - 11.28m2 per roll
type: Product
description: 120mm Knauf FactoryClad Roll 40 is a glass mineral wool insulation roll for built-up metal roof and wall systems, and the only 120mm roll in the FactoryClad family. The 32 grade is made in 80mm alone, and the 35 grade steps from 100mm straight to 140mm, so where a specification asks for 120mm of cladding quilt the 40 grade is the one that answers it. The setting is steel-framed industrial, commercial and agricultural buildings, with the roll held in the cavity between the inner liner sheet and the outer profiled weather sheet. Each roll measures 9.40m by 1200mm and covers 11.28m², with 24 rolls to a pallet for 270.72m². A declared thermal conductivity of 0.040 W/mK produces a thermal resistance of exactly 3.00 m²K/W at this depth, and water vapour resistivity is 5.00 MNs/g.m. Published embodied carbon sits at 1.04 kgCO2e/m² across stages A1 to A3 and 1.38 kgCO2e/m² across A1 to C4. What a quilt does at its joints decides whether a build-up performs the way it was calculated. Rolls of glass mineral wool knit into one another and take up slight irregularities in the liner sheet instead of bridging them, and they hold that contact as the frame settles and moves. Rigid insulation cannot do this: it either fits or it leaves a void, and voids are where a designed U-value quietly disappears. At 120mm the quilt is also compressed and released as it passes each bracket, and recovering afterwards is part of what keeps the layer continuous. Installation runs in the usual sequence: liner sheet fixed, quilt laid over it, spacer system brought up, outer sheet fixed, all to Knauf Insulation's guidance and the cladding system manufacturer's details. Spacer height and fixing lengths want confirming against 120mm before ordering, since this depth generally needs the bracket schedule looked at rather than assumed. It suits new-build twin-skin roofs and walls, standing seam roofs, and re-cladding work where the target U-value has moved on from whatever the original build-up could reach…
